The Science

What is PhenoAge?

PhenoAge (Phenotypic Age) is an algorithm developed in 2018 by biologist Morgan Levine at Yale School of Medicine. It uses 9 blood biomarkers plus chronological age to estimate your biological age — how old your body actually "acts" in terms of health and mortality risk.

The algorithm was trained on data from over 11,000 adults in the NHANES III study. It predicts all-cause mortality, cardiovascular disease, diabetes, and cancer risk better than chronological age alone.

Reference: Levine ME et al. "An epigenetic biomarker of aging for lifespan and healthspan." Aging (2018).

FAQ

Frequently Asked Questions

What is PhenoAge?

PhenoAge (Phenotypic Age) is a biological age estimate developed by Morgan Levine at Yale in 2018. It uses 9 routine blood biomarkers plus your chronological age to predict how fast your body is aging compared to the average population.

How accurate is this calculator?

This calculator implements the exact published PhenoAge algorithm with coefficients from the original Levine 2018 paper, cross-referenced with the BioAge R package. The results match validated reference implementations.

Where can I get these blood tests?

All 9 biomarkers are part of a standard Complete Blood Count (CBC) and Comprehensive Metabolic Panel (CMP). You can request these from your doctor or order them through direct-to-consumer lab services.

Is my data stored anywhere?

No. All calculations happen entirely in your browser. Your blood test values are never sent to any server. Your data stays 100% private on your device.

How can I lower my PhenoAge?

Focus on the biomarkers with the highest impact in your results. Common strategies include regular exercise, a nutrient-dense diet, quality sleep, stress management, and addressing any clinical deficiencies with your doctor.

What is PhenoAge Acceleration?

PhenoAge Acceleration (PhenoAgeAccel) is the difference between your PhenoAge and chronological age. A positive value means your body is aging faster than average; a negative value means you are aging slower.
